provide asimple practicable and automa'ti-,

rally acting machine for taking up and winding on a core a strip ofweb-like material.

It is a further object of the invention to provide a reel adapted toreceive aplurality of cores and to provide for the rotation of the coresabout their own axes and through a given orbit toward a pick-upposition.

A further-object of the invention is to provide means automaticallyoperative to wind each of the severed portions continuously andseverally or bodily on a mandrel or support and to provide for theintroduction and removal of these mandrels without interrupting theoperation of the machine as a whole and without interrupting theoperation of the winding mechanism.

The invention possesses other objects and features of advantage, some.of which, with the foregoing, will be made manifest in the followingdescription of the preferred form of the invention which is illustratedin the drawings accompanying and forming part of the specification. Itis to be understood that it is not intended to limit the invention tothe embodiment shown by the said drawings and A feature of the inventionresides in means for automatically winding strips onto a core such forexample as a spool or tube during the continued operation of a webmachine and further feature provides for the ready introduction of thewinding tubes or spools into the winding means without interrupting theoperation of the apparatus as a whole. An embodiment of such windingmeans comprises a reel or core carrier consisting of a pair of axiallyspaced rings or plates, 100, secured on a shaft, 101, that is driven bya reduction gear, 102, engaging a complementary pinion, 103, on a shaft,104, geared in desired ratio by change gears, 105, in the gear train ofthe web machine. This winding reel shaft, 101, is arranged below cuttingoff means, 80-81, between which means and the reel there is provided aholding means including a roller,

- 106, having an angular velocity equal vto the stock feed and thestock, A, is pressed against the roller, 106, by a pressure roller, 107,yieldingly mounted as on a pair of carrier arms, 108, provided with ashaft, 109. The pressure roller, 107, is shown as operative just abovethe lower guide, 7 5, of the uide wires, 75, the latter wire beingdirected outwardly beyond the guide, 75. The reel plates 100 areprovided with diametrically opposite clutch means such means comprisinga yieldable pin or detent, 110, axially opposite to a clutch disc, 111,secured on a stub shaft, 112, on which is provided a driving pinion,113. There is adapted to be readily interposed be tween one of theYielding pins or pivots, 110,

and a clutch faee., 111, a mandrel, 114, having a disc or head, 115, atone end to engage the clutch face, 111, preferably frictionally so thatthere may be a relative sliding movement getween the driving clutch,111, and the manrel. ielding springs against which the head, 115, ears,the springs being indicated at 116.

The mandrels, 114, are provided with removable spools or tubes, 117, andwhen one of the'mandrels is placed between the clutch means on the reelthe mandrel is designed to be rotated into close juxtaposition to thedownwardly extending portion of the guide wires, 76. Before, reachingthis position the applied tube, 117, is supplied With a coat of paste bya feed roller, 118, contacting with the surface of the tube, 117. As theman- Such frictional means may include attached by thepaste to the tube,117, and this latter is rotatedso that the strip is continuouslywoundup'. To secure the desired speed of rotation of the mandrel, 114,with its tube, 117 the pinions 113, of the mandrels engage and aredriven by 'a master ear, 119, which is driven as by a sprocket c ainconnection,

120, in equal speed witp the feed roller, 106. The speed of-thereel i{such that by the time one of the mandrels, 11 4, has completed about180 movement the entire strip Wlll have been I wound on-one' of thetubes, 117, the latter can be readily withdrawn from the clutch meansand an empty tube applied. The pressure roller, 121, supports the web asit is picked up by a tube, 117.

Should the trailing end of the strip from the guide tend to curl, asitis released below the guide, 7 5, it ma be held back against the wires,76, by a b ast of air from a nozzle, 125. It is obvious also that theleading end of the strip as it advances toward position to be attachedto a core is retained in correct receiving position by means of this airblast.

The operation of the winding machine is as follows:

The web or stock A is' delivered by the feeding means shown generally inoutline in Fig. 1. This stock or web A is cut into sections as it isdelivered by the cuttingofi' means -81 thereby effecting the delivery ofthe web in successive sections- The reel or core carrier ineluding,-a spreviously described, a shaft 101 rotatably mounted in the frame of thewinding machine and plates 100 presenting core supporting members, fixedto the shaft is operated from the main driving member of the'windingmachine through the shaft carrying the .feed roller 106 and a powertransmission mechanism, constituting the core carrier actuating means,connected between the shaft of the roller 106 and the shaft 101. As thecore carrier is operated, the cores mounted on mandrels 114 are placed1n the core receiving means consisting of the stub shafts 112 and theyielding detent 110 carried by the .-':--These pinions or operatingmeans are engaged by an operating member such for example as the mastergear 119 shown in Fig.

3;,and aredriven thereby.- The master gear j'. .l1}).is driven from theshaft of the feed roller 1061through the chain and sprocket connection120. "Therefore the core carrier is autotion and as the cores move inthis orbit they are rotated by the' core revolving means. After a corehas been mounted inthe core carrier, it is rotated on its axis whilecarried into contact with a roller 118 which applies paste or adhesiveof any desired kind thereby providing for the attachment of the web tothe core as the latter moves through the web receiving position adjacentthe pressure roller 121. The actuating mechanism for the core carrierand the core revolving means are so arranged that the portion of thecore coated with adhesive is presented to the web when the core arrivesat its web receiving position-adjacent the pressure roller:

tion is completed. Afterthe websection has passed from the feedingmeans, it is guided by the guide wires 7 5 and 7 6 and, after the guidewires cease to function, by the pneumatic means 125. After the websection has been completely wound on the core, the operator,bywithdrawing the yielding detent 110, removes the roll from the carrierand inserts a new core. a
